PMO Set up for a 2.7 ?
 

I just bought a set of 40 Pmo's from a fellow pelican. Can anyone suggest jets etc for a 2.7 S Cis euro engine with early exhaust and 2 in 2 out muffler ?

57 idles
180 airs
135 or 140 mains

Thanks John,

Would that be with 32 or 34 venturi ?

CIS cam ?

Call or fax Richard at PMO. Do whatever he suggests.

My setup was computed by Steve Weiner and Richard Parr.
I am running stock cams and stock pistons. Only mods on the motor is the heads which were
fly cut for a slight bump on compression. I believe the previous owner left the ports
the same.

40mm bodies
34mm venturies
135 mains
F11 Emulsion tubes
55 Idle jets
130 idle air jets
190 Air corrections jets

I believe I am running a little rich as my motor runs about 10 degrees cooler now than with the
CIS. I still need to get the car dynoed and check the AFR under load to find out for sure. This setup seems to pull hard and the motor breaths real healthy.

Mine were 34 venturies. I'm at sea level.

I just went through this with Richard at PMO last week. You want 34 venturis, 140 mains, F2 emulsion tubes, 55 idles, 180 air correctors for a street car or 36 venturis and 150 mains for a more track oriented car.
